Practice research networks (PRNs) have been proposed as a mechanism to support continuous service evaluation and improvement in the field of psychological therapies. In theory, PRNs could help to generate high quality practice-based evidence that has potential to inform and improve clinical care. However, in practice, many obstacles pose challenges to the sustainability and impact of such networks. The UK Northern Talking Therapies PRN is an exemplar that has generated over 20 scientific publications over a decade of successful clinical-academic collaborations. This article distils key lessons learned over that time, to guide and promote the wider adoption of PRNs in psychological services.

Empirical studies often have to work with incomplete samples, with scholars rarely accounting for under-registration: in cultural heritage e.g. the age-long loss of artefacts can yield an under-estimation of the original richness of assemblages. Recently, it has been argued that unseen species models from ecology can estimate the unobserved diversity in cultural collections. We report an extension on shared diversity, i.e. the number of types that are common to two assemblages. As a case study, we use stories in medieval French and Dutch (ca. 1150–1450), which were frequently shared. We apply an established estimator (Chao-shared) with a novel bootstrap procedure. The estimator suggests that the surviving data underestimate the original number of shared stories: for example, when its source is no longer extant, a translation can no longer be identified as such. Interestingly, there is less evidence for the total loss of shared stories: precisely because of the redundancy caused by inter-vernacular translation, shared stories were less likely to be lost in both languages simultaneously. These results go beyond previous studies in that they provide more insight into the composition of the unobserved share of cultural diversity (instead of its mere size).

This article examines the rise of conspiratorial thinking in wartime Russia as a response to a deeper collective anxiety – not merely the replacement of people, but the erasure of narrative agency. While the Russian version of the ‘Great Replacement’ echoes familiar Western themes such as elite betrayal, cultural erosion, and demographic decline, its central concern shifts towards symbolic displacement. Drawing on Mark Sedgwick’s interpretation of the Great Replacement as a stable narrative structure and J.V. Wertsch’s concept of narrative as a cultural tool, this article argues that conspiracy operates here as a means of reclaiming authorship in a national story whose core meanings have grown unstable. The analysis draws on social media discourse, pro-war commentary, volunteer statements, and nationalist media, showing how anxieties are shaped through emotionally resonant storylines of betrayal and erasure. Yet the reassertion of control paradoxically intensifies fragmentation, turning the Great Replacement into a narrative of narrative disappearance – where the gravest loss is not demographic, but symbolic.

The sequential units of language (i.e. words) have often been characterized by a tension between diversity and universality in the triangulation between information content, length and frequency. Here we examine similar tensions in the sequential units of visual narratives (i.e. panels) by focusing on how many entities appear per panel in visual narratives from the TINTIN Corpus of 1,030 annotated comics from 144 countries (76,000+ panels). Rates of entities per panel differ in regularized ways between styles of comics that cut across global regions, implicating typologically different ‘visual languages’. Entities per panel were also associated with panel size, where greater numbers of entities were associated with larger sizes of panels. Finally, a negative association appeared between panels with different numbers of entities and their frequency, reminiscent of a Zipf’s law of abbreviation. As associations of both size and frequency with character per panel persisted in a uniform way across styles, it implies universal tendencies transcending the diversity across systems, consistent with typological properties of languages.

Caregiver sensitivity to infant cues is well-established as a predictor of child development. Infants also actively influence their social environment, especially their caregivers, even from their earliest days. Sensory reactivity, characterized as hypo- (under) and hyper- (over) responding to environmental stimuli, is one domain of development that is likely to influence caregiver-infant interaction, due to its role in regulating emotions and responses to both physical and social stimuli. Although sensory reactivity could be an important target for improving caregiver-child interaction, the longitudinal, reciprocal relations between infant sensory reactivity and caregiver behaviors are currently unknown. In the present proof-of-concept study, we examined these associations in a community sample of mother-infant dyads (N = 252) at infant ages 6 and 12 months using a cross-lagged panel modeling approach. Preliminary findings, which will benefit from replication using a validated measure of sensory reactivity, indicated that maternal sensitivity may decrease infant hyperreactivity, and infant hyporeactivity may be associated with increases in maternal sensitivity. Maternal intrusiveness appears to exacerbate infant hyperreactivity over time and attenuate later infant hyporeactivity. The results of this study provide preliminary evidence for the mutually influential nature of infant sensory reactivity and maternal behavior and signals the importance of future investigation of these concepts.

This study investigated the independent and interactive effects of dietary behaviors and physical activity on poor sleep quality among 15,059 Chinese adolescents. Using a cross-sectional design, we assessed sleep quality (Pittsburgh Sleep Quality Index, PSQI), dietary habits, and physical activity. Logistic regression and interaction analysis were performed to examine associations, adjusting for covariates. The prevalence of poor sleep quality (PSQI score ≥ 7) was 9.72%. Seven healthy dietary behaviors were identified as protective (e.g., regular diet, abstaining from alcohol; ORs=0.49–0.56). While physical activity showed no independent association, limiting screen-based sedentary screen time(≤2h/day) reduced poor sleep odds by 31% (OR = 0.69). Two significant interactions emerged: abstaining from alcohol combined with limiting sugary beverages synergistically reduced the odds of poor sleep quality by 42% (OR = 0.58), whereas the combination of healthy dining out and high physical activity was associated with a 181% increased odds of poor sleep quality (OR = 2.81). While healthy dietary patterns are strongly associated with better sleep quality, the interplay between behaviors is complex, demonstrating both synergistic protective association and antagonistic outcomes. Findings highlight the need for integrated lifestyle interventions that account for behavioral interactions in promoting adolescent sleep quality.

Dual subtitles, combining captions (audio transcription) with subtitles translated into another language, are increasingly used in language learning. However, how they shape visual attention remains unclear. In the present experiments, we tracked the eye movements of Spanish–English bilinguals, as they viewed instructional videos with either no subtitles (Experiment 1) or dual subtitles (Experiment 2), manipulating subtitle position and audio language. Without subtitles, L1 audio focused gaze on the speaker’s eyes, while L2 audio distributed it between the eyes and mouth. With dual subtitles, gaze shifted strongly to the text, with a preference for the top line, which attracted more viewing time regardless of language. Viewers selectively attended to the line matching the audio. Comprehension improved for L2 audio with subtitles, while L1 comprehension was unaffected. Our findings demonstrate that display layout and language alignment jointly govern attentional allocation in bilingual viewing, with direct implications for L2 instructional design.

Depression among women living with HIV affects their psychological well-being, HIV disease management, and prevention of mother-to-child transmission. A subset of 25 women selected from the intervention arm of the Maternal Depression Treatment in HIV (M-DEPTH) cluster randomized trial were interviewed; they had received either antidepressant therapy (ADT) or problem-solving therapy (PST). Their experiences as new mothers with the effects of depression and treatment on HIV disease and pregnancy management were assessed in a brief qualitative interview conducted in 2022. Seven were treated with ADT, 15 with PST, and three received both treatment modalities; all but two (n=23) responded to depression treatment. Participants reported improved adherence to HIV antiretroviral therapy and described the treatment as being effective in alleviating depressive symptoms. Additionally, the process of treatment helped them to learn a lot about depression, mental health, and its connection to physical and emotional well-being. Participants also reported improvements in parenting and pregnancy management. The results highlight the need for greater prioritization of mental health care for women living with HIV to prevent poor mental health outcomes and enhance overall functioning, including management of HIV disease, pregnancy, and parenting.

Bilinguals vary in their daily-life language use and switching behaviours, which are also frequently studied in relation to other processes (e.g., executive control). Measuring daily-life language use and switching often relies on self-reported questionnaires, but little is known about the validity of these questionnaires. Here, we present two studies examining test–retest reliability and validity of language-use questionnaires (relative to Ecological Momentary Assessment, Study 1) and language-switching questionnaires and tasks (relative to recorded daily-life conversations, small-scale Study 2). Test–retest reliability and validity of the LSBQ (Anderson et al., 2018) were high and moderate, respectively, suggesting this questionnaire can capture daily-life language use well. Although only examined with a small sample size, Study 2 suggested relatively low validity of most language-switching questionnaires, with short language-production tasks potentially offering a more valid assessment. Together, these studies suggest that tools are available to reliably capture language use and switching with (a certain degree of) validity.

Previous research has highlighted that supplementing standard group-level event-related potential analyses with assessments of individual variation can enhance our understanding of language-related brain activity. The present study pursues this approach by examining bilingual speakers’ brain responses to morphologically complex word forms in both their native (German, L1) and their second language (English, L2). We tested 108 bilingual speakers using an ERP violation paradigm examining overapplications of regular verb inflections (‘regularizations’) and of irregular ones (‘irregularizations’). We found a striking L1/L2 contrast within the same bilingual speakers, a left-anterior negativity for regularizations in the L1 and a positivity (P600) for both violation types in the L2. Consistent with previous research, individuals’ brain responses were found to vary along negativity-/positivity-dominant effects. However, the crucial L1/L2 contrast in participants’ brain responses to regularizations was stable across individual differences. We conclude that linguistic constraints, that is, violation type and language status (L1 vs. L2), limit individual variability.

Mobile health (mHealth) interventions offer promising ways to enhance access and continuity of mental health services in low-resource settings. However, little is known about the perspective of end users in routine primary care in Nigeria regarding the role of mHealth in mental health care. This qualitative study explored the perspectives of patients, caregivers and healthcare providers on the use of mHealth tools to support access to and continuity of mental health care in Nigeria. Seventeen participants, including persons with lived experience of depression (n=7), caregivers (n=3), and primary healthcare workers (n=7), were purposively recruited from nine primary health clinics in Ibadan. Interviews were conducted in Yoruba, transcribed, translated into English, and analysed inductively using NVivo 15. Participants identified phone calls, Short Message Service (SMS) reminders, and audiovisual content as key facilitators of engagement, self-care and adherence. Caregivers valued direct communication with providers, while healthcare workers used mobile tools for reminders, follow-up and patient education. Flexible use of next-of-kin contacts helped overcome digital barriers. The findings demonstrate that user-friendly mHealth tools are feasible for supporting mental health care in Nigeria, but their success depends on coupling technology with human-centred communication to ensure equitable and continuous care.
